Default RE: Ed Kazmurski's Taurus

Here are a few still pictures taken in Lexington as the Taurus-2 stretched its wings once more. As with all "new" planes, it needs to be fully trimmed out.

The decision hasn't yet been made whether or not to stay with the vintage Super Tigre .56, or convert over to another engine, (such as an OS .50-.60), that was specifically designed to fly with a muffler. Right now the ST is not running/idling reliably...it has a little over an hour's worth of fuel that has been run through it, and should run better in the future. The carb on that engine is "weird", and not the best in the world. I have 3 ST .56 engines, and the carb on each seems to be a little different, almost like they were trying to find the right configuration to use. We may swith-out carbs to see which works best.. It seems common to drill out the stanbdard size hole to allow more air.

We will also do some experiments with modifying the add-on Tatone muffler by drilling it out some to allow more flow through. I was just told yesterday that the Tatone model I have is an "engine killer" in that the expansion chamber is supposedly not large enough and the engine has to work harder, thus they tend to run HOTTER. I also have a different brand of add-on muffler that is much more flow-through to test as well.

While not wanting to "overfly" the Taurus, I am looking forward to fine-trimming the plane and getting the engine peaked to be able to see just what theTuarus-2can do. Flights are relatively short on the six ounce tank that Ed called for, (maybe 8 minutes), so each flight will have to have a definite purpose in mind.
